Video Game Car Sound Library Audio

I’m building an arcade-inspired racer and need a comprehensive, highly realistic audio package that still feels fast and fun. The core requirement is a neatly organised library of production-ready WAV or MP3 files I can drop straight into Unity or Unreal.

Here’s what I’m looking for:

• Engine loops and one-shots for sports cars and electric cars – idle, low, mid, high RPM, plus hard limiter bursts
• Seamless acceleration / deceleration ramps that blend naturally into those loops
• Supporting effects: turbo hiss, nitro boost, backfire pops, tyre-squeal drift layers
• Dynamic pass-by whooshes at multiple speeds and distances

Delivery expectations
1. Clearly labelled folders by category (e.g., Engines_Sports, FX_Turbo, Ambience_Tunnel)
2. 48 kHz / 24-bit WAV (MP3 mirrors optional)
3. Clean loops trimmed to sample accuracy and normalised to consistent loudness
4. No copyright-encumbered recordings – all sounds must be original or fully licensed to me

When you reply, please include:
• A few links to previous game-audio or vehicle-sound projects
• Brief overview of your recording / design process and tools (e.g., Zoom F8n, Soundminer, Reaper, FMOD)
• Your total price and estimated turnaround time, including revisions

I aim to choose a freelancer quickly and get rolling, so feel free to showcase any demo material that demonstrates the roaring realism I’m after.
